Sysmex® XN Methodologies

 

  • Includes hematocrit (Hct), hemoglobin (Hgb), platelet count (PLT), RBC count; RBC indices: mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV); WBC count, and an automated differential. A manual differential is performed when indicated. 
  • RBC morphology is performed on non-oncology patients when indicated by abnormal RBC indices.
  • Abnormal results may be submitted to a pathologist for review upon physician request.
